Syllabus

Catchment hydraulics. Behaviour of flows in channels; open channel flow; uniform equilibrium and gradually-varied flows; hydraulic modelling; culvert design.

Outline

Subject purpose: The aim of the subject is to develop a sound understanding of the fundamental fluid mechanics principles and their application to professional water engineering problems. Fundamental fluid mechanics principles are applied to professional water engineering problems. As a result of undertaking the subject, each student will comprehend the hydraulics of rivers and canals, and grasp the basic catchment processes.

Subject rationale: The term 'Hydraulics' is related to the application of the Fluid Mechanics principles to water engineering structures, civil and environmental engineering facilities: e.g., canal, river, dam, reservoir, water treatment plant.In the subject, the students are introduced to the hydraulics of a catchment : rainfall, runoff and streamflow. The section "Introduction to Open channel flows" applies the basic principles of fluid mechanics to open channel flows. Examples of open channels are natural streams and rivers. Man-made channels include irrigation and navigation canals, drainage ditches, sewer and culvert pipes running partially full, and spillways. The lecture draws upon the students' expertise in catchment hydrology and water runoff gained in Hydrology Part of the subject. The teaching is focused on the application of the fundamental principles to open channel flow. The interactions between hydrology and hydraulics (e.g. rainfall and river discharge) are further discussed and the students are introduced to real-world engineering situations including failures. At the end of the subject, the design of a hydraulic system is introduced based on a system approach. The hydraulic structure must be analysed as part of the surrounding catchment and the hydrology plays an important role. Structural and hydraulic constraints interact, and the design of a hydraulic structure is a complex exercise altogether. First the system must be identified. What are the design objectives ? What are the constraints ? What is the range of options ? What is the "best choice" ? Its detailed analysis must be conducted and the engineers should ask : is this solution really satisfactory ? During design stages, physical and computational models may be reliable 'tools' to compare the performances of various design options.After completion of the subject, each student will know how to apply the fundamental fluid mechanics principles to professional designs and they will be familiar with the multi-disciplinary aspects of an engineering project.
Assumed background: The subject is a professional subject. It is expected that the students have mastered the fundamental principles of fluid mechanics (subject CIVL2131). The subject is the first of a series of two subjects (CIVL3140 and CIVL4120) dealing with river engineering, hydraulic structures and their interactions with the environment.

Lecture Material

Applications of the Bernoulli Equation to Open Channel Flows
2. Application of the Bernoulli equation - Specific Energy
2.3 Specific energy
    Typical applications of the Bernoulli principle and specific energy concept include the sluice gate in a horizontal channel (photo: (1), (2), (3), (4), (5) ; ref: Roth & Hager), the broad-crested weir overflow (photo: (1), (2), (3), (4) ).
    Critical flow conditions take place when the specific energy is minimum. Further discussion on the concept of minimum specific energy includes CHANSON (2006, 2008).

3. Froude Number
    The Froude number is proportional to the square root of the ratio of the inertial forces over the weight of fluid. The Froude number is used generally for scaling free surface flows, open channels and hydraulic structures. Although the dimensionless number was named after William FROUDE, several French researchers used it before. BELANGER (1841), DUPUIT (1848) and BRESSE (1860) highlighted the significance of the number to differentiate the open channel flow regimes. BAZIN (1865a) confirmed experimentally the findings. Ferdinand REECH introduced the dimensionless number for testing ships and propellers in 1852. The number is called the Reech-Froude number in France (CHANSON 1999, pp. 39-46).
    In rectangular channels, the Froude number is commonly defined as the ratio of the flow velocity to the square root of the product of g times d, where d is the flow depth and g is the gravity acceleration.

4. Properties of Common Open-Channel Shapes
    In practice, natural and man-made channels do not have often a rectangular cross-section. Critical flow conditions are defined as the flow conditions for which the mean specific energy is minimum (CHANSON 1999, pp. 46-48). In a horizontal channel and assuming hydrostatic pressure distribution, critical flow conditions imply :

g Ac3  =  Bc Q2
where Ac and Bc are respectively the cross-section area and free surface width at critical flow conditions, and Q is the flow rate.

Applications of the Momentum Principle : Hydraulic Jump, Surge, Flow Resistance in Open Channels
2. Hydraulic jump
    A hydraulic jump is a stationary transition from a rapid (supercritical flow) to a slow flow motion (subcritical flow). Although the hydraulic jump was described by LEONARDO DA VINCI, the first experimental investigations were published by Giorgio BIDONE in 1819 and the first theoretical analysis was conducted by BELANGER (1841). It is extremely turbulent and characterised by the development of large-scale turbulence, surface waves and spray, energy dissipation and air entrainment (eg CHANSON and BRATTBERG 2000). The large-scale turbulence region is usually called the 'roller'. Experimental observations highlight different types of hydraulic jumps, depending upon the Froude number of the upstream flow. An undular hydraulic jump is observed at low Froude numbers (1< Fr <3): looking downstream (Fr=1.2) and sideview (Fr=1.6). With increasing Froude numbers, other types of jumps include weak jump, oscillating jump (3.5< Fr <4.5), steady jump and strong jump (Fr >10).
    These photographs show surfers riding on a hydraulic jump roller in a river in Munich, Germany (Photo No. 1 : flow from right to left, Photo No. 2: looking downstream, Courtesy of Dale YOUNG).

3. Surges and Tidal Bores
    A surge in an open channel is a sudden change of flow depth (i.e. abrupt increase or decrease in depth). An abrupt increase in flow depth is called a positive surge while a sudden decrease in depth is termed a negative surge. This picture shows an undular surge (propagation from left to right).
    A positive surge looks like a moving hydraulic jump. The application of the momentum principle to the unsteady flow is based upon a quasi-steady flow situation analogy (CHANSON 1999, pp. 67-71).
    A bore is a positive surge of tidal origin. Tidal bores occur as the tidal flow turns to rising (e.g. Lynch 1982) (Links : (1) ). Famous ones include the Hangchow (or Hangzhou) bore on the Qiantang river (photo: (1),  (2) , (3) ), the Amazon bore called pororoca (photo: (1), (2) , (3) ; info: see below ), the tidal bore on the Seine river (mascaret) (photo: (1) ; info: (2) ), the Hoogly (or Hooghly) bore on the Gange, the bore on the Mekong river. Smaller tidal bores occur on the Severn river near Gloucester, England (photo : (1), (2) , (3) ), on the Trent river (aegir) (photo: (1)), on the Garonne and Dordogne rivers, France (photo: (1), (2) , (3); info: (3) (4) ), at Turnagain Arm and Knik Arm, Cook Inlet (Alaska) (info: (1) ; photo: (2) , (3) ), the bores in the Bay of Fundy (New Brunswick, Nova Scotia) like at Petitcodiac (info: (1) ), tidal bores on the Styx river QLD and on the Daly river NT (Australia), the tidal bore called benak at Batang Lupar (Malaysia) (photo (1)).
    The front of a positive surge absorbs random disturbances on both sides of the surge and this makes the positive surge stable and self-perpetuating. With appropriate boundary conditions, a tidal bore may travel long distances upsteam of the river mouth. For example, the tidal bore on the Pungue river (Mozambique) is still about 0.7 m high about 50 km upstream of the mouth and it may reach 80 km inland.
    Hubert Chanson observed the tidal bore of the Dordogne river on 27 Sept. 2000 (5:00pm).  The bore propagates first in the Gironde before separating and continuing both in the Garonne and in the Dordogne (Map). At St Pardon, the tidal bore was an undular bore on the 27 Sept. 2000. Photographs No. 1 and 3 illustrate the undular nature of the positive surge. Photo No. 1 shows the arriving bore. Photo No. 2 illustrates kayacks and surfers riding the bore. Photo No. 3 was taken just downstream of St Pardon while Photo No. 4 was shot in front of St Pardon.

4. Flow resistance in open channel flows
    In open channel flows, flow resistance can be neglected over a short transition  as a first approximation, and the continuity and Bernoulli equations can be applied to estimate the downstream flow properties as functions of the upstream flow conditions and boundary conditions. But the approximation of frictionless flow is no longer valid for long channels. Considering a water supply canal extending over several kilometres, the bottom and sidewall friction retards the fluid, and, at equilibrium, the friction force counterbalances exactly the weight force component in the flow direction.
    The laws of flow resistance in open channels are essentially the same as those in closed pipes. In an open channel, the calculations of the boundary shear stress are complicated
by the existence of the free surface and the wide variety of possible cross-sectional shapes. The boundary shear stress equals :
    to  =  f/8 r V2
where f is the Darcy-Weisbach friction factor and V is the mean flow velocity (HENDERSON 1966, CHANSON 1999). As for pipe flows, the flow regime in open channels can be either laminar or turbulent. In industrial applications, it is commonly accepted that the flow becomes turbulent for Reynolds numbers larger than 2000 to 3000, the Reynolds number being defined for pipe and open channel flows as Re = V*DH/n where DH is the hydraulic diameter or equivalent pipe diameter.     The Darcy friction factor f may be calculated as a function of the relative roughness ks/DH and Reynolds number from the Moody diagram
    In open channels, the Darcy-Weisbach friction equation (see above) is valid using the hydraulic diameter as equivalent pipe diameter. It is the only sound method to estimate the energy loss. For various reasons (mainly historical reasons), empirical resistance coefficients (e.g. Chézy coefficient) were and are still used. The Chézy coefficient was introduced in 1768 while the Gauckler-Manning coefficient was first presented in 1865 : i.e., well before the classical pipe flow resistance experiments in the 1930s. Historically both the Chézy and the Gauckler-Manning coefficients were expected to be constant and functions of the roughness only. But it is now well recognised that these coefficients are only constant for a range of flow rates. Most friction coefficients (except perhaps the Darcy friction factor) are estimated 100%-empirically and they apply only to fully-rough turbulent water flows (CHANSON 1999). In practice, only the Darcy-Weisbach friction factor must be used for man-made channels.

Note : The Gauckler-Manning equation is often called improperly the Manning equation. In fact it was first proposed by the Frenchman P.G. GAUCKLER in 1867 (GAUCKLER 1867) based upon the re-analysis of experimental data obtained by H.P.G. DARCY and H. BAZIN (DARCY and BAZIN 1865). Robert MANNING (1816-1897), chief-engineer at the Office of Public Works, Ireland, presented two flow resitance formula in 1890. One was the 'Gauckler-Manning' formula but Robert MANNING did prefer to use his second formula.

Culvert design
A culvert is a covered channel of relatively short length designed to pass water through an embankment (e.g. highway, railroad, dam). It is a hydraulic structure and it may carry flood waters, drainage flows, natural streams below earthfill and rockfill structures. From a hydraulic aspect, a dominant feature of a culvert is whether it runs full or not.
The design can vary from a simple geometry (i.e. box culvert) to a hydraulically-smooth shape (i.e. MEL culvert, photo No. 1 & photo No. 2). The lectures review first the design of standard culverts, then the design of minimum energy loss culverts.

Laboratory experiments

Open channel hydraulics
General information - Experiment description - Time schedule (see Blackboard)
Laboratory work is closely linked with the lecture program and it is an integral part of the hydraulics course. Four experiments are conducted during the semester.
Two experiments are linked to basic open channel flows: a study of a broad-crested weir overflow (photo) and the hydraulic jump (photo No. 1, photo No. 2). The former (broad-crested weir) is a smooth transition from an upstream sub-critical flow to a  downstream supercritical flow. The latter (hydraulic jump) is the transition from an upstream supercritical flow to a downstream subcritical flow.
The students conduct two further experiments on culvert design (photo) and backwater effects in a long channel (photo No.1, photo No. 2). The main purpose of the frmer experiment is to understand the differences between the hydraulic performances of two different types of culverts carrying the same flow rate (photo No. 1, photo No. 2). (Read about the minimum energy loss culvert.). The purpose of the long channel experiment is to demonstrate open channel control features, and to quantify friction and backwater effects in waterways. In each case, the experimental procedure includes observations, prediction (numerical modelling) and evaluation (comparison between data and computations).
